Airborne anti-submarine plays a very important role in the whole anti-submarine defense system.As the essential part of airborne anti-submarine,sonobuoy deployment system and its path planning's performance will affect directly the subsequent task of anti-submarine,and even make the whole anti-submarine task failed with bad planning.With its flight velocity and also the ability of submarine and anti-submarine,fixed-wing anti-submarine aircraft has become widely accepted.Because of the turning radius is too large under the deployed speed,the ordinary linear programming algorithm is unable to make the sonobuoy deployment task completed in time,so that the sonobuoy can not search the certain sea area in the best time.In this paper,the traditional ant colony algorithm was applied to the buoy deployment path planning of helicopter.Then we improved the fixed-wing aircraft and solved the problem that the minimum turning radius of fixed-wing planes is too large and the planes cannot deploy sonobuoys in time.The improved algorithm was proved to have good optimization and convergence performances with many simulations.
